Functional Features

Voltage Detection

S-80952CNNB-G9NT2G accurately detects the voltage level applied to its input pin and compares it with the preset threshold voltage. When the detected voltage falls below the threshold, the reset output becomes active low, indicating a voltage drop or power loss.

Reset Signal Generation

Upon detecting a voltage drop below the threshold, the S-80952CNNB-G9NT2G generates a reset signal on its output pin. This signal can be used to trigger a system reset or initiate specific actions to ensure proper device operation.

Delay Circuit

To prevent false resets caused by temporary voltage fluctuations, this IC incorporates a built-in delay circuit. The delay time is approximately 100ms, allowing sufficient time for the voltage to stabilize before generating a reset signal.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• High accuracy in voltage detection
• Low quiescent current consumption
• Compact package size for space-constrained applications
• Built-in delay circuit prevents false resets

Disadvantages

• Limited number of available threshold voltage options
• Requires external components for manual reset functionality (if needed)

Working Principles

The S-80952CNNB-G9NT2G operates based on a voltage divider network connected to its input pin. The voltage at this pin is compared with the preset threshold voltage levels internally. If the detected voltage falls below the threshold, the reset output becomes active low, indicating a voltage drop or power loss.

Detailed Application Field Plans

The S-80952CNNB-G9NT2G finds applications in various electronic devices where voltage monitoring and reset functions are crucial. Some potential application fields include:
